Zoot changes to light blue fleece skin and a yellow-green nose. He also starts wearing his hat all the time. (During the first season, the only times that he wore his hat were mainly during the At the Dance sketches and when he was performing with the Electric Mayhem.)

Debuting in Episode 314 of The Muppet Show and used the rest of the season, Zoot's skin color has changed to bright green and he's back to exposed foam.His nose turns yellow for the remainder of The Muppet Show.

Zoot changes back to blue fleece skin and a yellow nose. He now has gray hair and wears a gray/black spotted shirt and braces. His hair color has probably changed to avoid blue screen problems as most of the MuppeTelevision scenes have matted backgrounds.

Zoot's hair changes back to blue. Complete with his not yellow-green, but dark yellow nose, he now closely resembles his Muppet Show Season 2 self. His costume and glasses are adjusted to match the contemporary setting for this appearance and his appearance in Muppet Treasure Island.

Zoot has returned to his classic wear, though with updated, less rounded glasses. His hair also appears to be less curlier than before. His nose is light green, similar to how it looked on The Muppet Show.
